Superior mesenteric artery aneurysm: A report of two cases.

Two cases of superior mesenteric artery (SMA) aneurysm were reported; one with atherosclerosis and the other was mycotic in origin. Preoperative investigations included plain radiography, ultrasonography, computed tomography with contrast injection, angiography and nuclearscanning. SMA aneurysm was then diagnosed and the patient underwent operation. Results of the operations were satisfactory. It is suggested that early and correct diagnosis is critical in minimizing morbidity and mortality in the patients with SMA aneurysm.
